Catalytic Treatment and Clean Energy team (TCEP)

Research Area :

 The main theme of the team is about « heterogeneous catalysis applied to the environment. » The catalytic remediation is explored for (1) the removal of air pollutants, and (2) the proposed alternatives for the production of clean energy. These two aspects will better take into account the complexity of the chemical composition of industrial or automotive waste and provide a catalytic solution.


Catalytic treatment of air pollutants (VOCs, Soot, NOx, CO)

The studied catalysts are based on precious metals (Au, Pd) or transition metal oxides (Cu, Co, Fe, …) supported on simple or highly structured porous oxides. The underway studies are about the problem of air pollutants in its entirety by multifunctional catalysts. In the context of different national and international research programs especially about VOCs, several orientations were chosen as following:

1. Development of catalysts that can oxidize representative industrial mixtures (for all types of VOCs).
2. Development of the mechanistic approach in the reactions and the methods of physicochemical characterization « in situ » or « Operando ».
3. Development of highly structured porous inorganic materials to obtain solids with good properties both provide for support catalysts in adsorption/absorption. Such materials are the subject of study on the Fenton reaction for the degradation of organic pollutants.
4. Study of the by-products of the reactions that can occur during a catalytic treatment both at the start of the reaction and at the end of the catalyst’s life. A study of the toxicity of these gas mixtures is then performed by the team « Chemistry and Toxicology of Atmospheric Emissions « .

Production of hydrogen from the valorisation of pollutants

Like electricity, hydrogen is an energy carrier with the advantage of the store. Associated with the fuel cell, it provides an opportunity for clean energy production (industry, transport …).
We study the production of hydrogen coming from catalytic reforming of renewable resources such as biogas, methane, methanol and ethanol produced from biomass. A key concern is the development of efficient catalytic systems (high activity and low selectivity to CO) and this at the lowest possible temperatures for avoiding catalyst deactivation (coking, sintering, leaching, poisoning …). These catalysts are based on transition metal oxides (Co, Cu, Ni, Zn, …) supported on alumina (Al2O3) and / or ceria (CeO2) or hydrotalcite, doped or not with noble metals. Extensive studies on the mechanistic aspects and parameters affecting the activity and selectivity as well as aging are undertaken to optimize the performance of the studied systems.
